NOTE

Exploring Genotype by Environment Interactions in Cattle Performance

Genotype by environment interactions play a crucial role in cattle performance. The concept of G by E, or genotype by environment, focuses on understanding how interactions between genotype and environmental factors affect animal traits and outcomes. The study showed that environmental sensitivity, particularly in response to water restriction, influenced feed intake and performance. While population-level environmental sensitivity was evident, individual-level responses showed limited variability. Animals that performed well under no water restriction also performed well under high levels of water restriction, indicating minimal re-ranking or significant impact of G by E in this scenario.
